Would someone pls share how to calculate the accustat rating. I played real good against the 9 ball ghost last night and I'm just curious what my accustat would be. I think besides keeping score it would be good way to keep track of progress. Thanks.

Direct link to the PDF that gives details.

Basically, divide [balls made] by [balls made + errors].

Accustats vs. the ghost would be a little weird because it's meant to account
for normal gameplay like kicks, safes, breaks, etc.
None of which are a concern playing the ghost.

In your case the only thing you'd track are misses and position errors.

Miss a tough shot = 1 error. Tough means anything harder than a spot shot.
Miss an easy shot = 2 errors.
Position error = every time you don't run out, you get
charged with a position error on top of your miss.
Scratches also are position errors, even on the break.

So every loss to the ghost would be a minimum of 2 errors.
The miss and the position error.

Would you automatically consider reaching for a shot (very makeable with a rake) a positional error?

So you are saying even a runout does not necessarily get a perfect score. Am I right?

I think I will include losing control of the cb on the break as an error.

Leaving a stretch I don't consider an error. You don't get position errors for leaving yourself long,
so it makes sense you don't get them for leaving yourself 'short'.
Anyway what's a stretch for one player is easy for another so it's subjective.

If they miss due to stretching, they get charged 2 errors (1 for the position, 1 for the miss,
like all other misses).

Losing control of the CB on the break = an error... I think that's strict but fair.
Maybe don't charge the error if the cue ball visibly stops and squats, and then
some other ball kicks it somewhere.

Under current accustats rules the only way you run out but lose points is
if you scratch on the break.

If we modified the rules to be more realistic then yeah you could lose more points.
Let's say playing shape on the 4 you get stuck behind the 8. You try to kick it and succeed.
You still screwed up for hooking yourself and it should be counted as an error.
